SHUTTLE EYE OR THREADER.

Specification of Tietters Patent.

Patented m 31, 1917.

Application filed August 2, 1915. Serial No. 43,191.

To aZZ whom it may concern:

Be it known that I, lVILLIAM B. BROWN, a citizen of the United States, residing at Westminster, in the county of Oconee and State of South Carolina, have invented certain new and useful Improvements in Shuttle Eyes or Threaders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the'same.

This invention relates to an eye orthreader to be used in hand-threading loom shuttles, and the primary object of the invention is to provide an eye or threader which, owing to its peculiar construction, will maintain uniform tension on the yarn, and also to provide an eye or threader which is not dependent on the woodwork of shuttles at the external opening, and which will preserve the tension of the yarn, will not unthread, no matter what particular cut the outside of the shuttle requires, and further a threader or eye which will carry any kind or type of yarn from fine to coarse material.

Another object of this invention is to provide a shuttle eye or threader as specified, which is provided with a slot in one end of the same, by means of which the eye or threader may be turned within the shuttle for increasing or decreasing the tension on the yarn.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangements of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure l is a front view of the delivery end of a shuttle, showing the improved eye or threader attached thereto,

Fig. 2 is a side elevation of the delivery end of a shuttle, showing the invention applied to the same,

Fig. 3 is a longitudinal section on the line 3-3 of Fig. 1,

Fig. l is a section on the line l4 of Fig. 1, and

Fig. 5 is a perspective view of the eye or threader, and I Fig. 6 is an end view of the eye or threader.

Referring more particularly to the drawings, l designates the delivery end of a shuttle, which delivery end is provided with a transversely extending opening 2 which communicates with a groove 3 formed in one side of the shuttle body. The opening 2 communicates with an opening formed in one face of the shuttle, which opening 4L communicates with the bobbin-holding portions of the shuttle.

The opening 2 has the eye or threader 5 mounted therein. The eye or Vthreader 5 is cylindrical in shape and is provided with a centrally disposed bore 6 extending throughout a portion of the length of the same. The eye or threader 5, is provided with a longitudinally extending slot 7, which communicates with the bore 6 and with an opening 8, that extends diametrically through the eye substantially equidistant of its ends. The slot 7 is used as an outlet for the thread or yarn as it passes out of the shuttle. An oblique slot 9 communicates with the opening 8 and extends through substantially one-half of the eye or threader 5. The oblique slot 9 communicates with a slot 10, which is cut in the wood of the shuttle, as is clearly shown in dotted lines at 11 in Fig. 4 of the drawings. The slot 10 extends along the sides of the shuttle, and communicates with the slot 7 formed in the eye 5, which construction of slot permits of the free and easy threading of the shuttle.

The end of the eye or threader 5, remote from the end which is provided with the bore 6, has a groove or recess 12 formed therein, and extending diametrically across the same. By slightly turning the eye in the shuttle the tension on the thread or yarn can be increased or decreased as desired, as it can be seen that when the flattened surface of the eye is slightly turned the surface thereof engages the thread or yarn, thus increasing the tension on the thread or yarn, and when the flattened surface is positioned downward the thread or yarn can easily slide out of the slot 7, thus decreasing the tension on the yarn or thread. The groove 12 is provided for receiving a screw driver, for turning the eye after it has been inserted within the shuttle, for increasing or decreasing the tension on the thread or yarn passing therethrough. When it is die sired to regulate the tension of the yarn by rotating the eye 5, the pin 17 is forced out of the opening let.

The eye 5 is provided with an opening 1% extending diametrically through the same, which is tapered, as is shown in Fig. l. The opening 14k is provided for alinement with openings 15 and 16 formed in the body 1 of the shuttle, and a tapered pin 17 is inserted through the opening 1% for preventing accidental movement or turning of the eye or threader 5, within the shuttle. By means of the slot 12; the eye can he readily turned to position the opening la in a1inement with the opening 15 in the shuttle, so

that the pin 17 can he easilyinserted.

In reducing the invention to practice, certain minor features of construction, combination, and arrangement of parts may necessitate alteration, to which the patentee is entitled, provided such alterations are comprehended within the scope of what is claimed.

hat is claimed is r A guide eye for hand threading shuttles comprising a tubular body including a central longitudinal bore opening out at one end, and a flat face on its under side, said face extending from said open end to a point short of 'the other end of the guide eye and provided with a longitudinal slit in communication with the here, said body having openingsthrough its upper side and said face relatively alined and located at the inner end of said slot, and said body having a second slit extending diagonally from said openings and opening out through one side of the body at a point inwardly beyond the inner end of the first slit.

In testimony whereof I affix my signature in presence of two witnesses;

WILLIAli i B. BROWN.
